Making CACHE_L2X0 depend on (huge list of MACH_ and ARCH_ configs)
is bothersome to maintain and likely to lead to merge conflicts.
This patch moves the knowledge of which platforms have a L2x0 or
PL310 cache controller to the individual machines. To enable this,
a new MIGHT_HAVE_CACHE_L2X0 config option is introduced to allow
machines to indicate that they may have such a cache controller
independently of each other.
Boards/SoCs which cannot reliably operate without the L2 cache
controller support will need to select CACHE_L2X0 directly from
their own Kconfigs instead. This applies to some TrustZone-enabled
boards where Linux runs in the Normal World, for example.
